Cabin noise

Guard Dad · 01-13-2011, 11:09 PM

I grow weary of posts that deal with the cabin noise issue with a curt "live with it". The forum is here to support its members with information about our favorite car, not to slam members because they don't share our exact same priorities for enjoying the 370Z.

For those who track the Z, brakes and oil temperatures are big issues. Since many of us don't tack the Z not everyone will share those concerns, but you don't see people telling the racers among us to "live with it" when it comes to fading brakes or high oil temperatures. On the contrary, people are eager to offer help and advice on how to alter that car to best address the needs of that particular owner. I think that it is fair to expect nothing less when it comes to cabin noise or any other Z related issue. If you can't post something helpful, perhaps you shouldn't post at all.

With the selective use of aftermarket products the Z can be a race car, a sports car or a luxury GT. I can't understand why the hardcore preformance types get so worked up when some among us would occasionally like to enjoy a little peace and quiet at the end of a long day.

On another matter, several times I have seen posts lecturing about the proper use of Dynamat and Mass Loaded Vinyl (MLV) soundeadner. By now most everyone knows that Dynamat is more for resonance and is not the ideal product for sound reduction and that it works best in conjunction with a MLV like Luxury Liner Pro or a similar product. Theory aside, I have used both products in the hatch area of my Z and I have to say that an application of Dynamat (about 85% coverage) made a BIG difference. The improvement form adding Luxury Liner Pro over the Dynamat was noticeable but not that big of a deal. I have posted liberally on this very thread about my experiences with both products.

That has been my experience too.. the car was far too noisy for me and my wife but an application of Dynamat in the hatch and doors made a huge difference. I am now planning to dynamat the wheel wells.
Dynamat saved me.,. I absolutely could not stand the loud noise. What was meant to be a pleasant fun trip for my wife and I and turned into a buzzsaw the very first day!!..but now that has changed

. just in time for 18 inches of snow!!

Guard Dad,

Thanks for all your excellent info on quieting this beast down. Why live with annoying levels of noise unless you only care about performance? Your posts have been very helpful in helping me to decide what methods to use.

I'll let everyone know how mine turns out.
